To all whom t may concern.'

Be it known that LLEE H. WILSON, a citizen of the United States, residing at 1Westgate, California, have invented a new and useful Feed-Gage, of which the following is a specification.

My object is to make a feed gage for platen printing presses which will not des stroy the tympan sheet and which will be capable of a great variety vof adjustments without removal lfrom the press and which 'will assure accurate alinement of the printed work.

My invention consists of the novel features herein shown, described and claimed.

In the drawings-Figure 1 is a fragmentary side elevationof the parts of a platen press which carry the platen and an end view of the platen, showing my feed gage in position for use', the view being taken as indicated by the arrow l in Fig 2. Fig. 2 is a fragmentary plan view of the platen and adjacent partsA as indicatedby the arrow 2 in Fig. 1, showing the feed gage in position for use. Fig. 3 is a fragment-ary sectional detail on the line 3 3 of Fig.-2 and looking in the direction indicated by the arrow. Fig. 4t is a sectional detail on the line 1 4 of Fig. 2. Fig. 5 is a sectional detail on the lines 5 5 of Figs. 2 and 3. Fig. 6 is a perspective detail of the bottom or horizontal gage bar. Fig. 7 is a fragmentary perspective of the upper end of the vertical or side gage bar.

Referring to the drawings in detail-the lower or horizontal gage bar 1 is a rectangular plate having a flange 2 turned from its upper edge and teeth 3 extending from the flange. When the gage bar is in position against the tympan, the teeth 3 rest upon the tympan under pressure sufficient to prevent the liability of the card 4 (or other material to be printed) from slipping down back of the gage bar. The adjustable finger 5 is inserted through slots in the gage bar and extends upwardly from the flange 2. The finger 5 may be moved up and down through the gage bar as desired. Teeth 6 extend from the lower end of the finger 5 to engage the tympan and hold the finger in its adjusted position. A link 7 is con-y Specicaton of Letters Patent.

patented Jaiy 2s, i914.

second link is connected to an attaching plate l1 by a rivet 12. The rivets 8, 10 and r12 should be set tight enough to make comparatively stiff joints and loose enough so that they may bemoved ywhen desired. The attaching plate 11 is of considerable length and flanges 13 and 14 extend at right angles from the lower edge of the plate 11 and are adapted to be inserted between the lower edgeof the press platen 15 and the lowerbail 16. In making up the parts', the links 7 and 9 should be bowed suciently so that whenthe attaching plate 11 is in posit-ion, the gage bar 1 will be pressed against the tympan. It is obvious that the gage bar 1 may be moved without destroying the tympan. kl\l`otches 17 are formed in the `upper edge of the attaching plate 11.

The side or vertical gage bar 18 has ay finger 19 extending one way from its upper end to pressv against the tympan, and a finger 20 extending the other way. The bar 18 is of considerable length and is pivotally attached to a 'clip 21 which embraces the attaching plate 11 and has a tooth 22 to fit in any desired one of the notches 17, so that the side gage may be readily adjusted. A spring 28 is rigidly connected to the clip 21 and slidingly connected to the bar 18, the tension of the spring being exerted to throw the upperl end of the side gage outwardly away from the work. The lower end of the bar 18 extends a considerable distance below the clip 21 and above the gripper bar 24. A piece of sheet metal is cut and shaped to form the base 25 and the inclined cam 26. The base 25 is placed against the gripper bar and a wing-nut 27 and bolt 28 is applied to hold the cam 26 in the desired position. The lower end of the bar 18 works against vthe cam 26 so that when the platen is back to receive the work and the gripper finger 29 is up, vthe lower end of the bar 18 4rides upon the cani 26 and the spring 23 throws the upr moving the sheet and jogging it so that it will settle down uponthe lower gage vand produce perfectly alined work. The side gage bar is vibrated back and forth `at each operation of the press.

Thus I have produced a feed gage having a lower or horizontal gage bar which may be readily adjusted or moved to any desired position and having a vertical or side gage bar which may be readily adjusted or moved to any desired position and which vibrates at each operation of the press, so as to move or jar the work down upon the lower gage bar, and a feed gage which may be used many times and adjusted to many positions without destroying the tympan.

The details of construction may be varied in many ways without departing from the spirit of my invention as set up in the following claim.

I claimln a feed gage an attaching plate having notches in its upper edge; flanges extending backwardly at right angles from the lower edge of the attaching plate and adapted to be inserted between the lower edge of a press platen and the lower bail; a vertical gage bar; a linger extending from the upper end of the vertical gage bar and adapted to press against the press tympan; a clip embracing the attaching plate, said vertical gage bar being pivotally connected to the clip; a tooth extending from the clip and adapted to engage the notches of the attaching plate, a spring rigidly connected to the clip and slidingly connected to the gage bar, the tension of the spring being exerted to throw the upper end of the gage bar outwardly, the lower end of the gage bar extending a considerable distance below the clip and adapt-` ed to t above the gripper bar ot the press; a base adapted to I'it against the gripper bar; and an inclined cam extending from the base over the gripper linger of the press so that the lower end of 'the gage bar will work against the cam thereby moving the gage bar in and out upon the tympan.
